Seroprevalence data indicate that West Nile virus (WNV) activity is present in Turkey; however, no pediatric cases of WNV infection have been reported to date. WNV is an emerging flavivirus in Turkey, and in September2010, the Turkish Ministry of Health reported the first seven cases of laboratory-confirmed WNV infection from five different cities in the western part of the country. This is the...

BACKGROUND West Nile virus infection in humans in urban areas of the Midwestern United States has exhibited strong spatial clustering during epidemic years. We derived urban landscape classes from the physical and socio-economic factors hypothesized to be associated with West Nile Virus (WNV) transmission and compared those to human cases of illness in 2002 in Chicago and Detroit. The objective...

Prior to 1999, West Nile virus (WNV) was a bit player in the screenplay of global vector-borne viral diseases. First discovered in the West Nile District of Uganda in 1937, this Culex sp.-transmitted virus was known for causing small human febrile outbreaks in Africa and the Middle East. Prior to 1995, the last major human WNV outbreak was in the 1950s in Israel. The epidemiology and ecology of...

The evolutionary relationships among pathogen lineages in multi-host systems are often the only observable signature of unobserved ecological and epidemiological processes. The evolution of viruses infecting humans, particularly, is of interest because of the public health importance of understanding the relationship of virus exposure to disease risk. Here I report results of two analyses of th...

Induction of interferon beta (IFN-β), IFN-stimulated genes (ISGs), and inflammatory responses is critical for control of viral infection. We recently identified an essential linkage of stimulation of the inflammatory cytokine interleukin-1β (IL-1β) and induction of ISGs that function as host restriction pathways against the emerging flavivirus West Nile virus (WNV) in vivo Here we utilized ex v...
